As shown in FIGS. 1 to 12 , the examples of the present disclosure disclose a light emitting assembly 100 and a lamp. The light emitting assembly 100 includes a base portion 110, a conductive portion 130, a light source 120, and a transparent insulating layer 140, and the base portion 110 is a rigid structure. It should be noted that the rigid structure refers to that the base portion 110 is made of a rigid material, and in normal use, the base portion 110 hardly deforms. However, in the process of production and processing, due to the corresponding production requirements, the base portion 110 may also be deformed to a certain extent under set conditions with sufficient external force or high temperature adjustment, so that the base portion 110 may be made into a specific shape and structure according to design requirements and customer needs, and the base portion 110 is not unable to be deformed in an absolute sense.

The conductive portion 130 is disposed on a surface of the base portion 110, and the conductive portion 130 and the base portion 110 are insulated from each other, thereby ensuring that the lamp has a better safety performance. The light source 120 is installed on the surface of the base portion 110 where the conductive portion 130 is located, and the light source 120 is electrically connected to the conductive portion 130 to transmit electric energy to the light source 120 through the conductive portion 130. In order to prevent electricity leakage in the conductive portion 130 and the light source 120 during the operation of the lamp, the conductive portion 130 and the light source 120 are both covered with the transparent insulating layer 140.

The base portion 110 is formed of a rigid material, such as a polymer material, a composite material, a metal material, and the like. The shape and size of the base portion 110 may be determined according to actual conditions such as usage scenarios and customer needs. Optionally, the base portion 110 may be made of a metal material, on the one hand, it is easy to process and the cost is relatively low, on the other hand, the metal material component has a longer service life and a better appearance effect.

In order to further improve the structural strength of the base portion 110 and prevent the base portion 110 from being bent or deformed during the use of the lamp, optionally, the base portion 110 may be an aviation aluminum component, that is, the base portion 110 may be formed of an aviation aluminum material, so that the base portion 110 has a stronger structural strength, and the base portion 110 is basically not rusted after being used for a period of time, and the service life is relatively long. During the processing of the base portion 110, the base portion 110 may be made to have a smaller thickness to further reduce the installation space occupied by the lamp, and because the aviation aluminum material has a stronger tensile strength, the base portion 110 with a relatively small thickness can also have a strong structural strength, and it can basically ensure that the base portion 110 will not be deformed during the use of the lamp. In addition, in the case that the thickness of the base portion 110 is relatively small, the aesthetics of the lamp can be enhanced, and the comprehensive competitiveness of the product can be improved.

More specifically, the base portion 110 may be a strip structure, or the base portion 110 may also be a ring structure such as a circular structure, a rectangular structure, a polygonal structure, or the like. In the design and production process, the shape and size of the base portion 110 may be changed according to specific conditions such as usage scenarios and customer needs.

Since the metal material has the advantages of better conductivity, lower cost, and less difficulty in processing, the conductive portion 130 may also be made of a metal material. During the processing of the light emitting assembly 100, the conductive portion 130 may be formed in advance, and the conductive portion 130 and the base portion 110 are connected as a whole during the processing of the base portion 110. In the case that the conductive portion 130 is located on the surface of the base portion 110, the entire base portion 110 can have a stronger structural strength to ensure that the entire lamp has better structural stability. Furthermore, if the lamp fails, the location of the fault can be found quickly with the help of the conductive portion 130 on the surface of the base portion 110, which is convenient for maintenance. Of course, the conductive portion 130 fixed on the surface of the base portion 110 may be formed by other methods.

Optionally, the conductive portion 130 may be fixedly connected to the base portion 110 by the manner of pressing. A relatively large adhesion force can be formed between the conductive portion 130 and the base portion 110 under a certain pressure, and the weight and size of the conductive portion 130 is relatively small, so that the conductive portion 130 will not fall off the base portion 110. The size and the number of the conductive portion 130 may be determined according to actual conditions such as the rated current of the light source 120 and the number of the light source 120.

The light source 120 may be an LED lamp or other types of components with light emitting function. The size, rated voltage and other parameters of the light source 120 may be determined according to actual requirements, and are not limited here. The light source 120 is installed on the surface of the base portion 110 where the conductive portion 130 is located. Since the base portion 110 is a rigid structure, the base portion 110 can provide a stable installation foundation for the light source 120. The light source 120 may be installed on the surface of the base portion 110 in an embedded manner, and the light source 120 and the conductive portion 130 may be electrically connected during the assembling process of the light source 120.

Furthermore, the light source 120 may be a lamp bead. In order to further improve the lighting effect of the entire lamp, a plurality of the light source 120 may be provided. The brightness of the entire lamp and the illuminated area can be improved under the action of the plurality of the light source 120. In addition, the plurality of the light source 120 may be arranged on the base portion 110 at intervals, and the plurality of the light source 120 are all electrically connected to the conductive portion 130 to ensure that each light source 120 can work normally under the action of an external power source.

As described above, the base portion 110 may be a strip or ring structure. Accordingly, in the case that the shape of the base portion 110 is different, the arrangement form of the plurality of the light sources 120 may be determined according to the actual shape of the base portion 110. For example, in the case that the base portion 110 has a strip structure, the plurality of the light sources 120 may be arranged in a single column and multiple rows, or the plurality of the light sources 120 may be arranged in double columns and multiple rows, or the plurality of the light sources 120 may be arranged in multiple columns and multiple rows. Similarly, in the case that the base portion 110 has a ring structure, the plurality of the light sources 120 may be arranged in a ring shape, and the number of circles of the ring may be determined according to actual conditions.

The transparent insulating layer 140 may be a structure formed by curing a material such as a transparent insulating glue. During the processing of the light emitting assembly 100, the transparent insulating layer 140 may be formed outside the conductive portion 130 and the light source 120 by the manner of dipping, painting or spraying after the conductive portion 130 and the light source 120 are fixed on the base portion 110. The thickness of the transparent insulating layer 140 may be determined according to parameters such as operating current of the lamp. In addition, the thickness of the transparent insulating layer 140 may be made as small as possible under the condition that the lamp has a good safety performance, so as to minimize the hindrance and weakening effect of the transparent insulating layer 140 on the light emitted by the light source 120.

Optionally, the transparent insulating layer 140 may be made to filter light of a specific wavelength band according to actual requirements such as usage scenarios. For example, parameters such as the type and composition of the transparent insulating layer 140 may be changed so that the transparent insulating layer 140 can filter blue light with a wavelength of 400 nm-480 nm in the light emitted by the light source 120, so that even if the lamp disclosed in the examples of the present disclosure are used for a long time, it will not cause harm to human eyes. Alternatively, the material of the transparent insulating layer 140 may also be changed so that the transparent insulating layer 140 can have a certain diffusion effect on light.

More specifically, the transparent insulating layer 140 may be a glue layer formed by curing a UV (Ultraviolet Rays) glue. The UV glue has no volatiles, does not cause environmental pollution, has a fast curing speed, and has a low demand for curing conditions, which can improve the processing efficiency of the lamp. In addition, the low flammability of the UV glue can further improve the safety performance of the lamp. Moreover, the UV glue can be repeatedly applied and cured for many times, which is convenient for the production of the lamp and the maintenance of the lamp.

In the case that the above-mentioned light emitting assembly 100 is applied to a lamp, the conductive portion 130 may be electrically connected to the power access portion 200 to provide power to the light source 120. In the case that the base portion 110 is an insulating structure, even if the conductive portion 130 is charged during normal operation, the electricity will not be transmitted to the base portion 110, thereby ensuring that the base portion 110 has good insulation during the operation of the lamp. As mentioned above, the base portion 110 may also be made of a metal material, in the case that the base portion 110 is a metal structure, other insulating structures such as the transparent insulating layer 140 may be provided between the conductive portion 130 and the base portion 110, so as to ensure a good insulation performance between the base portion 110 and the conductive portion 130. In the case that the transparent insulating layer 140 is formed of a UV glue, and the transparent insulating layer 140 is provided between the base portion 110 and the conductive portion 130, the connection reliability between the conductive portion 130 and the base portion 110 can be further improved.

Furthermore, the light source 120 may have a sheet structure. As shown in FIG. 1 and FIG. 2 , a size of the base portion 110 in a thickness direction of the base portion 110 may be D1, a size of the light source 120 in the thickness direction of the base portion 110 may be D2. In order to ensure that the light source 120 has a better installation firmness, D1 is larger than D2. In order to reduce the size of the entire light emitting assembly 100, the ratio of D1 to D2 may be 2˜8, which can reduce the installation space occupied by the entire light emitting assembly 100, and can improve the appearance of the light emitting assembly 100 to a certain extent, and improve the overall performance of the product.

In addition, a size of the base portion 110 in a width direction of the base portion 110 may be B1, and a size of the light source 120 in the width direction of the base portion 110 may be B2, B2 is greater than B1, and the ratio of B1 to B2 may be 2˜4, thereby further reducing installation space occupied by the light emitting assembly 100, and improving the appearance effect of the light emitting assembly 100.

In an example, in the case that the width B2 of the light source 120 is 1.4 mm and the thickness D2 of the light source 120 is 0.5 mm, the thickness D1 of the base portion 110 may be 3 mm, and the width B1 of the base portion 110 may be 4 mm.

As described above, the examples of the present disclosure further disclose a lamp. The lamp may be a ceiling lamp, a floor lamp, a wall lamp, etc. The lamp includes a power access portion 200 and the above-mentioned light emitting assembly 100. In addition, the light emitting assembly 100 may be fixedly installed on an installation foundation such as a wall or a roof using a fixed structure. For example, in the case where the power access portion 200 is a rigid structure, the light emitting assembly 100 may be fixedly installed directly through the power access portion 200.

Specifically, during the use of the lamp, the power access portion 200 may be connected to an external power source, that is, the power access portion 200 is connected to a power source provided externally. In addition, the light source 120 can work normally under the action of the external power source by electrically connecting the power access portion 200 and the conductive portion 130. Moreover, since the power access portion 200 is fixed on the base portion 110, in order to prevent the power access portion 200 from introducing electricity to the base portion 110, the power access portion 200 and the base portion 110 may be insulated from each other.

Since the base portion 110 and the power access portion 200 are both rigid structures, the entire light emitting assembly 100 may be directly supported on the power access portion 200. During the use of the lamp disclosed in the present disclosure, by connecting the power access portion 200 with an external power source, the lamp can form an electrical connection with the external power source, and the lamp can also form a relatively fixed relationship with the external power source, thereby simplifying installation steps and improving installation efficiency during the installation process of the lamp. In addition, the light source 120 of the lamp disclosed in the examples of the present disclosure forms an electrical connection with the external power source without the use of the wire 250, so that the situation of serious decline in the installation performance of the lamp due to the broken of the wire 250 will not occur during the use of the lamp.

For example, the external power source may be a socket installed on the wall, and the power access portion 200 may include two metal conductive plugs. In the case of normal use of the lamp, the power access portion 200 may be inserted into the socket, so that the power access portion 200 can form an electrical connection with the socket. In addition, since the power access portion 200 and the base portion 110 are both rigid structures, as the lamp is electrically connected to the socket, a reliable physical connection can be formed between the lamp and the socket under the support of the power access portion 200 and the base portion 110. Since the lamp disclosed in the examples of the present disclosure does not need to use supporting parts such as suspension wires, connecting rods or brackets during the installation and fixing process, the installation process of the lamp can be simplified.

Specifically, since the metal material have the ability to conduct electricity, and most of metal materials generally have relatively high hardness, and can meet the hardness and conductivity requirements of the power access portion 200, therefore, optionally, the power access part 200 is formed of a metal material. Of course, in the case where other rigid materials have relatively good conductive effects, other materials may also be used to form the power access portion 200. The power access portion 200 and the base portion 110 may form a relatively fixed relationship by a riveting, clamping or plugging manner. Alternatively, the power access portion 200 may be provided with an external thread, and the base portion 110 is provided with an internal threaded hole, and therefore the power access portion 200 and the base portion 110 can be connected through the manner of threaded connection. Since at least two power access portions 200 are provided, in the case that the at least two power access portions 200 are connected to the same base portion 110 through threaded connection, it can be ensured that the base portion 110 is stably supported on the power access portion 200. Furthermore, the power access portion 200 and the base portion 110 may also be relatively fixed by means of other connection structures.

In order to further improve the lighting effect of the lamp, at least two light emitting assemblies 100 may be provided, and the at least two light emitting assemblies 100 are both electrically connected to the power access portion 200. The lighting effect of the lamp can be more intuitively improved by adding the light emitting assembly 100. The shape of the base portion 110 in each light emitting assembly 100 may be the same or different, and the arrangement and relative positional relationship of the at least two light emitting assemblies 100 may be determined according to actual needs, so as to form lamps with different shapes to meet different usage scenarios or different customer needs.

In the case that at least two light emitting assemblies 100 are provided, the number of power access portions 200 is correspondingly increased. Optionally, the at least two light emitting assemblies 100 may be at least partially overlapped with each other. In this case, the irradiation areas of the at least two light emitting assemblies 100 can be overlapped and supplemented to a certain extent, and the lighting effect of the lamp can be further improved.

In addition, in the case that the base portion 110 of each light emitting assembly 100 is in a ring shape, the total installation space occupied by all the light emitting assemblies 100 can be made smaller by making the at least two light emitting assemblies 100 at least partially overlapped. In detail, the overlapping part of the plurality of the light emitting assemblies 100 may be used as the part that is connected to the power access portion 200. In the case that the parts of each light emitting assembly 100 connected to the power access portion 200 are overlapped, the interval between the plurality of the power access portions 200 can be made smaller, the overall structure of the lamp is more compact, and the installation space occupied is smaller.

Correspondingly, an insulating interval may be provided between the power access portion 200 and the base portion 110. For example, the power access portion 200 and the conductive portion 130 are fixed to each other, and the power access portion 200 is not directly contacted with the base portion 110, so that it can be ensured that the base portion 110 and the power access portion 200 are insulated from each other, or the power access portion 200 and the base portion 110 may also be insulated from each other with the help of an insulating structure.

As mentioned above, the power access portion 200 and the base portion 110 may be directly connected to form a relatively fixed relationship, or the power access portion 200 and the base portion 110 may also be indirectly connected by another connecting component 420 to form a relatively fixed relationship. Optionally, the lamp disclosed in the present disclosure may include a fixing component 410, a through hole 111 may be provided on the base portion 110, and the power access portion 200 may include a limiting portion 210 and a connecting portion 220, and the limiting portion 210 is connected to the connecting portion 220. In the process of assembling the power access portion 200 and the base portion 110, the limiting portion 210 and the fixing component 410 are respectively located on both sides of the base portion 110, the limiting portion 210 is located on the side where the conductive portion 130 is located, the limiting portion 210 is electrically connected to the conductive portion 130, the base portion 110 can be mounted on the connecting portion 220 by allowing the connecting portion 220 to pass through the through hole 111 to be fixed to the fixing component 410. In addition, by sandwiching the base portion 110 between the limiting portion 210 and the fixing component 410 in an axial direction of the through hole 111, it can be ensured that the base portion 110 and the connecting portion 220 form a more reliable fixed relationship, the lamp can have better structural stability, and this connection method is simple and convenient.

Optionally, the fixing component 410 and the connecting portion 220 may be detachably connected to form a fixed relationship, and the light emitting assemblies 100 can be freely replaced according to different customer needs by providing a variety of light emitting assemblies 100. Correspondingly, after the lamp has been used for a period of time, if the lighting emitting assembly 100 fails or is damaged, the lighting emitting assembly 100 can also be removed, and the lighting emitting assembly 100 can be repaired or replaced with a new one, which can reduce the requirements for maintenance and repair. For example, the fixing component 410 and the connecting portion 220 may be fixed to each other by a detachable connection such as a clamping connection, a plugging connection, a threaded connection, or the like.

Specifically, the connecting portion 220 and the limiting portion 210 may be formed by integral molding, which reduces processing difficulty and improves production efficiency on the one hand, and can also improve the reliability of the connection between the connecting portion 220 and the limiting portion 210 on the other hand, and ensure that the light emitting assembly 100 can be stably supported on the power access portion 200 and the power access portion 200 can transmit electric energy stably.

The through hole 111 may be formed by drilling. By making the through hole 111 and the limiting portion 210 different in shape and/or size, the limiting portion 210 and the through hole 111 can form a reliable matching relationship for position restriction. Optionally, the connecting portion 220, the limiting portion 210, and the through hole 111 may all have a circular structure, by making the diameter of the connecting portion 220 smaller than the diameter of the through hole 111, and making the diameter of the limiting portion 210 larger than the diameter of the through hole 111, the connecting portion 220 can pass through the through hole 111 and be fixed to the fixing component 410 on the other side of the through hole 111, and it can be ensured that the limiting portion 210 and the through hole 111 can form a matching relationship for position restriction, and then it can be ensured that the base portion 110 and the power access portion 200 can form a stable fixed relationship.

As mentioned above, the base portion 110 may be made of a metal material. In the case that the base portion 110 is formed of the metal material and the connecting portion 220 passes through the through hole 111, in order to further ensure that the base portion 110 and the connecting portion 220 can be insulated from each other, the diameter of the through hole 111 may be larger than the diameter of the connecting portion 220, so that the connecting portion 220 and the base portion 110 are insulated from each other. In addition, the limiting portion 210 may only be in contact with the conductive portion 130 on the surface of the base portion 110, but not in contact with the base portion 110, so as to ensure that the limiting portion 210 and the base portion 110 are insulated from each other. Furthermore, the fixing component 410 may be made of an insulating material, so that even if the fixing component 410 and the base portion 110 are in contact with each other, the base portion 110 will not be in a charged state during the operation of the lamp.

Alternatively, during the production and processing of the lamp, the base portion 110 with the through hole 111 may be formed in advance, and then an insulating layer can be formed on the outer surface of the base portion 110. For example, the insulating layer may be formed of an insulating glue, which can also ensure that the power access portion 200 passing through the through hole 111 of the base portion 110 and being fixed to the base portion 110 can form a reliable insulating relationship with the base portion 110. Moreover, after the insulating layer is formed on the outer surface of the base portion 110, the conductive portion 130 and the base portion 110 are fixed together to ensure that the conductive portion 130 can also form a reliable insulating relationship with the base portion 110.

Optionally, in order to reduce processing difficulty and improve production efficiency, the lamp disclosed in the examples of the present disclosure may further include an insulating component 300, the insulating component 300 may be sleeved outside the connecting portion 220, and at least a part of the insulating component 300 is sandwiched between the connecting portion 220 and the base portion 110. It can be ensured that the connecting portion 220 and the base portion 110 form a more reliable insulating relationship under the insulation effect of the insulating component 300. Compared with the previous example, the implementation process of this insulation method is relatively simple, and the insulation effect is more reliable.

Specifically, the insulating component 300 may be a cylindrical structure made of an insulating material such as rubber. During the assembly process of the lamp, the insulating component 300 is inserted into the through hole 111 of the base portion 110, and then the connecting portion 220 passes through the through hole of the insulating component 300 and is relatively fixed to the fixing component 410 on the other side of the base portion 110, so that a relatively reliable fixing relationship can be formed between the power access portion 200 and the base portion 110, and a good insulation reliability between the connecting portion 220 and the base portion 110 can be ensured.

As mentioned above, the fixing component 410 and the connecting portion 220 may be fixed to each other through the threaded connection, this connection method is simple and easy, and the fixing effect is relatively good. In order to further improve the fixing effect and reduce the processing difficulty, both the connecting portion 220 and the fixing component 410 may be made of metal materials. In this case, in order to ensure that the base portion 110 can still form a better insulation effect with the power access portion 200, the insulating component 300 may include a first insulating portion 310 and a second insulating portion 320, and the first insulating portion 310 is connected to the second insulating portion 320, the first insulating portion 310 is sandwiched between the connecting portion 220 and the base portion 110, and the second insulating portion 320 is sandwiched between the fixing component 410 and the base portion 110.

In the case that the insulating component 300 adopts the above structure, a good insulation effect between the connecting portion 220 and the base portion 110 can be ensured, and a good insulation effect between the fixing component 410 made of a metal material and connected to the power access portion 200 and the base portion 110 can be ensured, and this insulation method is simple and convenient, and the processing and assembly of the lamp are less difficult. Moreover, in the case that the insulating component 300 is made of a rubber material, the degree to which the second insulating portion 320 is squeezed can be adjusted to achieve the purpose of improving the fixing effect between the base portion 110 and the power access portion 200. In addition, the second insulating portion 320 can also provide a protective effect for the base portion 110 to prevent the base portion 110 from being damaged in the case that the fixing component 410 and the connecting portion 220 are tightly connected.
